Security conference organizers and researchers constantly track Calls For Papers (CFPs) to plan submissions and attend relevant events. Managing this manually is tedious, and existing tools often overlook security aspects in their CLI outputs. cfpsec is a Python command-line utility that queries cfptime.org for upcoming security and hacking conference CFPs, designed with a clear emphasis on preventing injection attacks and ensuring safe terminal and CSV outputs.
What cfpsec does and how it is built
cfpsec is a Python CLI tool that fetches CFP listings from the cfptime.org API, a public repository of security conference data. It supports retrieving upcoming calls for papers and conference listings, with filtering options such as keywords, country, and days until the event. Users can paginate through historical conference data and view detailed information about individual conference entries.
The tool is built in Python 3.9+, leveraging the requests library for HTTP API calls and colorama for cross-platform terminal output coloring and readability. It handles multiple output formats including plain text, JSON, and CSV, accommodating different workflows such as direct terminal inspection or integration with spreadsheet tools.
Architecturally, cfpsec is structured as a CLI client with command-line argument parsing as the entry point, followed by API client modules managing request logic, and output formatter modules responsible for safe rendering to terminal or file. The use of colorama ensures consistent terminal coloring on Windows, macOS, and Linux, including automatic background color detection to avoid unreadable text.
The project is distributed under the GPL v3+ license and published on PyPI, making it accessible for installation in Python environments. Version 2.0 marked a significant update focusing on security hardening and robustness.
Defensive programming in a CLI for safer outputs
What makes cfpsec stand out is its attention to security hardening in areas often overlooked by CLI tools:
ANSI escape sequence sanitization: Terminals interpret ANSI escape sequences for colors and formatting, but malicious input containing crafted escape codes can perform terminal injection attacks, causing unwanted terminal behavior or information leakage. cfpsec sanitizes all external data before rendering, stripping or neutralizing potentially harmful escape sequences.
CSV formula injection protection: When exporting data to CSV, certain characters at the start of a field (like
=,+,-,@) can cause spreadsheet software to interpret the cell as a formula. This may lead to code execution or data leakage when users open CSV exports. cfpsec mitigates this by escaping or prefixing such inputs to neutralize formulas.Integer type enforcement on ID parameters: To prevent URL injection or malformed requests, cfpsec enforces strict integer typing on parameters like conference IDs, ensuring that the API client does not send unexpected or malicious input.
HTTP retry with exponential backoff: Network requests to cfptime.org can fail due to connectivity issues or rate limiting. cfpsec implements a retry mechanism with exponential backoff, improving reliability without overwhelming the API.
These defensive measures reflect a mindset of secure coding in CLI utilities, especially important in security tooling where data integrity and safe output are paramount.
In terms of code quality, the project is surprisingly clean for a niche CLI. The separation of concerns between argument parsing, API interaction, and output formatting is clear. Error handling is thorough, with user-friendly messages and safeguards against invalid inputs.
One tradeoff is that the tool depends on the availability and stability of the cfptime.org API, which is an external dependency outside the project’s control. Also, while the tool supports multiple output formats, handling very large datasets might require additional performance considerations.
Explore the project
The repository is straightforward for Python developers familiar with CLI tools. The main entry point is a CLI script that parses arguments to select filters and output formats. The README provides usage examples and describes available filters.
The source code is organized into modules handling HTTP requests to cfptime.org, parsing and sanitizing data, and formatting output safely for terminal or CSV.
Since no verified installation or usage commands are provided in the documentation, the best way to try cfpsec is to clone the repository and inspect the README for usage instructions or check PyPI for installation notes.
The README also notes the requirement for Python 3.9 or newer. The use of standard libraries and a minimal set of dependencies keeps the footprint small.
Verdict
cfpsec is a practical tool for security researchers, conference organizers, and attendees who want a simple way to track CFPs and upcoming security or hacking conferences from the terminal. It’s particularly relevant for those who appreciate safe CLI output practices to avoid injection risks, especially when exporting data.
The focus on sanitization and injection prevention in a CLI context is commendable and not common in similar utilities. This makes cfpsec a modest but solid example of defensive programming in security tooling.
Limitations include its reliance on an external API and the lack of a graphical or web interface, which may not suit all users. The CLI-centric design and Python implementation make it accessible to developers comfortable with the command line and scripting.
Overall, cfpsec is worth a look if you need reliable conference CFP data and want to avoid common pitfalls in CLI output security.
